DNS Record Types

Here are the 8 most commonly used DNS Record Types.

1. A (Address) Record
   Maps a domain name to an IPv4 address. It is one of the most essential records for translating human-readable domain names into IP addresses.
2. CNAME (Canonical Name) Record
   Used to alias one domain name to another. Often used for subdomains, pointing them to the main domain while keeping the actual domain name hidden.
3. AAAA Record
   Similar to an A record but maps a domain name to an IPv6 address. They are used for websites and services that support the IPv6 protocol.
4. PTR Record
   Provides reverse DNS lookup, mapping an IP address back to a domain name. It is commonly used in verifying the authenticity of a server.
5. MX Record
   Directs email traffic to the correct mail server.
6. NS (Name Server) Record
   Specifies the authoritative DNS servers for the domain. These records help direct queries to the correct DNS servers for further lookups.
7. SRV (Service) Record
   SRV record specifies a host and port for specific services such as VoIP. They are used in conjunction with A records.
8. TXT (Text) Record
   Allows the administrator to add human-readable text to the DNS records. It is used to include verification records, like SPF, for email security.
